Sarracenia on a Windowsill: Brown Tips Signal Insufficient Light

A grower has two 4-inch pot Sarracenia on a windowsill with brown, crusty pitcher tips. Asks what's wrong.

Diagnosis: Light Starvation

Sarracenia require full sun or very high supplemental light. Windowsills rarely provide enough. They weaken, brown, and die indoors without intense artificial light (e.g., 12,000 lumen fluorescent tubes 4" above plants, 16 hrs/day).

Seasonal Context

If it's late winter/early spring, plants may be emerging from dormancy—brown tips on old pitchers are normal. But long-term, they need outdoor sun or a serious indoor setup.

Next Steps

• Provide location, light hours, and season for specific advice.
• Plan to move outdoors in full sun when weather permits.
• Indoors: high-output fluorescent or LED grow lights essential.
